Fort Myers, Florida-based Golden Ratio Turbine Concepts (GRTC), a pioneering Golden Ratio rotary device creator, has built a new Golden Ratio Turbine. The new prototype is the most recent in the company’s “CYCLOTROSS ™” line of vertical axis wind turbines (VAWT), and it reveals a new innovative golden spiral wing design.
GRTC spokesman James Walker said the company’s previous smaller prototype success had prompted the development of a larger device that could be trailer-mounted and transported to remote areas as a temporary or prolonged power station. The VAWT has at its core a 1 KW-3 phase AC axial flux PMG generator and incorporates an intelligent 48-volt hybrid wind/solar AC/DC power converter/controller. The power load center compartment is in the rear of the trailer and houses the 4-deep cycle, 12-volt storage batteries along with the charge controller, a pure sinewave DC to 120 volt AC inverter, and the 3-cup anemometer wind speed display electronics.
As well as the 120-volt 60-cycle AC output, the station provides 12- and 24-volt DC ports for accessories and charging needs. The hybrid controller enables the combined inputs of a solar array and the new VAWT to provide clean power anywhere the sun shines and the wind blows (even on a floating barge or a mountain top), all of which creates a versatile new electrical power generator station that is adaptable to provide clean-energy solutions for a diversified variety of applications.
Walker said the new power station features a locking stow-pin mechanism in the rotor to prevent rotation when in transit. The rotor assembly also includes a mechanical brake apparatus on the pedestal (in addition to the electrical brake on the controller front panel). The modified utility trailer also has a removable wind shield (with logo) and a protective sleeve fitting over the rotor wings that minimizes apparent wind effects on the turbine while traveling. A retractable pivoting canopy top and framed side coverings provide storage of the station when not in use.
GRTC said an initial wind test demonstrated the new prototype exhibits the same features as its smaller counterparts and begins to charge the 48-volt battery bank in a light 9-mph breeze. Likewise, this newest golden spiral wind turbine is quiet and graceful to behold in motion.
